ABSTRACT:
An apparatus and method for performing a hydroforming process cause either or both of the opposed end portions of the workpiece to be deformed to achieve desired shapes therein. Initially, a workpiece having a pair of end portions is disposed within a die cavity defined by first and second die sections have cooperating recesses. A pair of end feed assemblies engage the end portions of the workpiece and deform such end portions to a desired shape. Pressurized fluid is provided within the workpiece either before, during, or after the deformation of the end portions of the workpiece to deform the central portion thereof it into a desired shape as defined by the die cavity.
